1. Introduction
The APsystems Energy Communication Unit (ECU-R) is the information
gateway for our inverters. The unit collects module performance data from
each individual inverter and transfers this information to an Internet
database in real time, requiring only a single data and power cable. Through
the APsystems Energy Monitoring and Analysis software, the ECU-R gives
you precise analysis of each inverter and module in your solar installation
from APP. The user-friendly interface lets you access your solar array in
seconds.
